Negotiation Support Systems and Methods

1. A system for negotiation support, comprising: a first computer, comprising a first negotiation agent module receiving a plurality of first proposals, calculating a first preference score (PS) for each first proposal using a first utility model, selecting a portion of the first proposals as a plurality of second proposals in descending order according to the first PSs therewith, receiving a plurality of third proposals, calculating a second PS for each third proposal using the first utility model, and arranging the third proposals in descending order according to second PSs therewith to generate a first voting result; a second computer, comprising a second negotiation agent module receiving the first proposals, calculating a third preference score (PS) for each first proposal using a second utility model, selecting a portion of the first proposals as a plurality of fourth proposals in descending order according to the third PSs therewith, receiving the third proposals, calculating a fourth PS for each third proposal using the second utility model, and arranging the third proposals in descending order according to the fourth PSs therewith to generate a second voting result; and a negotiation server, comprising a negotiation management module receiving the second proposals from the first negotiation module and the fourth proposals from the second negotiation module, generating the third proposals according to the second proposals and the fourth proposals, receiving the first voting result from the first negotiation module and the second voting result from the second negotiation module, and generating a final agreement according to the first voting result and the second result.

2. The system of claim 1 wherein the first negotiation agent module communicates with the negotiation management module via network.

3. The system of claim 1 wherein the second negotiation agent module communicates with the negotiation management module via network.

4. The system of claim 1 wherein the first utility model and the second utility model respectively use at least one formula to calculate the PSs according to selected items for issues in the proposals.

5. The system of claim 1 wherein the negotiation management module uses recombination process or mutation process of Genetic Algorithm (GA) to generate the third proposals.

6. The system of claim 1 wherein the negotiation management module generates the first proposals.

7. The system of claim 6 wherein at least one item for each issue in the first proposals is randomly selected.

8. A method for negotiation support, loaded and executed by a processing unit, comprising: the processing unit generating a plurality of first proposals; the processing unit receiving a plurality of second proposals being a portion of the first proposals; the processing unit receiving a plurality of third proposals being a portion of the first proposals; the processing unit generating a plurality of fourth proposals according to the second proposals and the third proposals; the processing unit receiving a first voting result corresponding to a portion of the fourth proposals; the processing unit receiving a second voting result corresponding to a portion of the fourth proposals; and the processing unit determining one of the fourth proposals as a final agreement according to the first voting result and the second voting result; wherein: the second proposals are determined by a first negotiation agent module; the third proposals are determined by a second negotiation module; the first negotiation agent module calculates a first preference score (PS) for each first proposal using a first utility model and selects a portion of the first proposals as the second proposals in descending order according to the first PSs therewith, and the second negotiation agent module calculates a second PS for each first proposal using a second utility model and selects a portion of the first proposals as the third proposals in descending order according to the second PSs therewith.

9. The method of claim 8 wherein the first utility model and the second utility model respectively use at least one formula to calculate the PSs according to selected items for issues in the proposals.

10. The method of claim 8 wherein the fourth proposals are generated using recombination process or mutation process of Genetic Algorithm (GA).

11. The method of claim 8 wherein the first voting result is generated by a first negotiation agent module, and the second voting result is generated by a second negotiation module.

12. The method of claim 11 wherein the first negotiation agent module calculates a first preference score (PS) for each fourth proposal using the first utility model and arranges the fourth proposals in descending order according to the first PSs therewith to generate the first voting result, and the second negotiation agent module calculates a second PS for each fourth proposal using the second utility model and arranges the fourth proposals in descending order according to the second PSs therewith to generate the second voting result.

13. The method of claim 8 wherein at least one item for each issue in the first proposals is randomly selected.

14. A machine-readable storage medium storing a computer program which, when executed, performs a method for negotiation support comprising: generating a plurality of first proposals; receiving a plurality of second proposals being a portion of the first proposals; receiving a plurality of third proposals being a portion of the first proposals generating a plurality of fourth proposals according to the second proposals and the third proposals receiving a first voting result corresponding to a portion of the fourth proposals; receiving a second voting result corresponding to a portion of the fourth proposals; and determining one of the fourth proposals as a final agreement according to the first voting result and the second voting result; wherein: the second proposals are determined by a first negotiation agent module; the third proposals are determined by a second negotiation module; the first negotiation agent module calculates a first preference score (PS) for each first proposal using a first utility model and selects a portion of the first proposals as the second proposals in descending order according to the first PSs therewith, and the second negotiation agent module calculates a second PS for each first proposal using a second utility model and selects a portion of the first proposals as the third proposals in descending order according to the second PSs therewith.
